Yes. Were you describing what happens now, or what you want to happen when you said "External mails server sends message and authenticates to the 2010 server..."? --- Rich Matheisen MCSE+I, Exchange MVP --- Rich Matheisen MCSE+I, Exchange MVP

Hi All, I have a scenario where I need to create a relay limited to a domain user account. External mails server sends message and authenticates to the 2010 server with the selected domain user account, the message is then relayed onto final destination. I can't simply create a receive connector and allow relay from the remote mail server because the vendor cannot guarantee its IP address will remain consistent (strange circumstance). So I simply need the relay to be allowed for my selected domain user. Is this possible? Many thanks in advance
